MEANS FOR MOVABLY SUPPORTING PATTERNS.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application fil ed nugust 28, 1913. I Serial No. 787,044.

To all whom it may concern Be it known that I, FRANK a citizen of the United States, residing at Hamilton, Ohio, have invented a new and useful Improvement in Means for Movably Supporting Patterns, of which the following is a specification.

My invention relates to means for mov ably supporting patterns adapted to use in connection with molders flasks, and the objects of my improvementare to provide a frame with members universally movable within its plane whereto a gate of patterns may be removably secured that the patterns.

may be vibrated independently of the frame or of the flask, and to provide simple and durable construction and assemblage of the various parts for securing facility of operation and efficiency of action. These objects may be attained in the following described manner, as illustrated in the accompanying drawings,-in which Figure 1 is a plan of a frame for movably supporting patterns and embodying my improvement; Fig. 2 an end elevation with parts in section, and Fig. 3 a section on the line aa, of Fig. 1.

In the drawings, 1 represents the bottom board with the drag and cope members 2 and 8 of a flask supported thereon, and 4 the flask pins, all being constructed and arranged in the ordinary manner. The open frame 5, preferably of metal and adapted to register with the walls of the flask, may be removably supported on the flask pins and between the drag and cope members as shown in Fig. 3. Said frame is formed with a plurality of horizontal mortises or openings 6 through its walls, and brackets 7 formed with tenons 8 of less width thanthe mortises may be extended therethroughfor supporting the brackets on the inside of the frame and permitting them to be moved to a limited extent in every direction in the plane thereof. A gate 9 provided-with patterns 11 may be rigidlyandyet removably secured to the brackets as by being soldered thereto at the points 12 thus making the brackets and gate of patterns substan .tially integral and movable simultaneously in any direction independently of and in the plane of the frame. An opening 18 through the gate 9 may have a pin removably inserted therein for rapping the pat terns in the mold in the usual manner. An

J Broken,

extension of one of the tenons as at 14 beyond the outside of theflask serves for the attachment thereto of an ordinary vibrator for rapping the patterns within the mold if desired. a t

In operation, the frame with the drag member thereon may be placed on the match or follow board in the inverted position and the drag portion of the mold completed in the usual manner. After the bottom board is in place the partially completed mold may be turned over and the match removed. The cope member may then be placed on the drag and completed as usual. The pattern may now be rapped universally within the plane of the frame in any desired manner as by means of the usual pin or by a vibrator. The cope and the frame with the patterns may then be successively removed and then the cope replaced on the drag and after the flask is removed the tenon holes may be closed with sand. l/Vhere a plate of patterns or where patterns rigidly secured to a frame are used, it is impossible to vibrate the patterns in relation to the flask owing to their required immovable relation to the flask pins.

The foregoing described improvement has all the advantages of the patterns formed on a plate or secured to a frame while retaining the advantages in rapping of patterns dis connected with the flask. I

Having fully described my improvement, what I claim as my invention and desire to secure by Letters Patent of the United States is 1. A molders flask comprising a frame adapted to be'removably secured between the separable members thereof, and movable connections with the frame for supporting a pattern withinthe flask whereby it may be jarred independently of the frame. 1

2'. The combination of a frame adapted to register with a molders flask, and means for movabl y securing a pattern therein.

3. The combination of a frame adapted to register with the separable members of a molders flask, and brackets loosely supported by the-frame for-supporting a pattern therein. a

4:. The combination of a flask, a frame removably secured between the cope and drag members thereof and in registration with the walls thereof, andv brackets supported within the frame and universally movable in the plane thereof, said brackets being adapted to be immovably secured to a pattern.

5. A molders flask comprising a frame adapted to be removably secured between and in registration With the separable members thereof, and brackets loosely connected With the frame for supporting a pattern therein.

6. A molders flask comprising a frame removably secured between and in registration with the Walls of its separable members, and means engaging with the frame and universally movable Within its plane for movably supporting a pattern therein.
